RCT Calibration Status Lindsey Gray
Previous Findings • Sucessfully fit ECAL TPG sum mean as a function of Et to a quadratic. • HCAL TPG sums were scaled by some factor, causing much confusion.
Current Progress • Finally getting reasonable HCAL Et measurements. Using HCAL transcoder directly now. • Next I am going to attempt to fit H/E as a function of Gen Et so I can scale Ecal and Hcal TPG sums to that I can add them in a meaningful way. • HCAL TPG seems to to start underestimating as a function of Et (using NI pions) • ECAL TPG over estimates (using photons).
